Smock



FIG. 1 is a perspective view of a smock, showing my new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a rear elevational view thereof;

FIG. 4 is a left-side elevational view thereof;

FIG. 5 is a right-side elevational view thereof;

FIG. 6 is a top plan view thereof; and,

FIG. 7 is a bottom plan view thereof.

The broken lines showing a child in FIG. 1 and a logo in FIGS. 1 and 2 depict environmental matter and form no part of the claimed design. 

I claim the ornamental design for a smock, as shown and described.
